www l To all -whomitjnay concern: i Be it known that I, MARTIN A.-EWALD,

aA citizenl ofthe United-- States, residing at Nicollet, in the county'of'.Nicollet, State of Minnesota, have invented' certain new and useful`Improvements in and Ijdo herebydeclare the following to beta full,

4 clea'r,. andf exact description" ofthe invention,`

*suchzas will enable others skilled in the art.

.10, to which it appertains to make and use the same. t v

` i The invention relates to a wheel and more particularly to the classof dust proof wheel boxes.

The primary object of the invention is the provision of a vwheel boxin-which the hub of the 'wheel may `Abe longitudinally adjusted upon thejournal end of the axle and` A further object of the inventioir is theprovision of a hub attaching devlce whlch flsvadapted for use on sulkyplow wheels or other agricultural implements and 'that 1s r readily andeasily assembled for connecting;r

the wheels tothe axles and also-that will from dust'and dirt.

. 'A still further object of the invention is thel provision of hubattaching devlce which is simple in construction, thoroughly 46 reliableand eliicient in operation and inexpensive in` manufacture. l -Withthese and other objects in v iew the invention consists in theconstruction, combination andarrangement of parts as will 5 behereinafter more fully described, illus-v trated inthe accompanyingdrawings, disi closing,the preferred form of embodiment of the inventionand-pointed out in the claims hereunto appended. In thedrawin -l 3`igure1- is a central longitudinal sectlonal view ofa wheel hub and axle' withthe invention applied thereto.

Fig. 2 is a sectional view on the line 2-2 of F1 c 1. i 45.6 Similarreference characters mdlcate correlieve the axle from'wear4 andprotectit views in the drawings. Y v

Referring to the drawings by numerals 5 designates the journal Tend ofan axle of the ordinary well-known construction on which is tted aninner sleeve 6 the saine surrounding the said axle and -is-provided atits outer end with van outturned annular flange" or shoulder 7 and thissleeve 6 has provided near its inner end at opposed sides, threadedopenings Vto be engagedy `by fastening screws 9] which are adapted tobind on the' o'uter'surface of the axle 5 andrhold-the said v.innersleeve 6.lo ngitudinally adjusted thereonil and from turning upon-thesaid axle.

responding parts throughout the several Surrounding theV inner sleeve6-is` an outer sleeve .formin a boxing 10 the latter being fitted 1n a hu11 andis adapted to rotate upon the innersleeveA 6, the inner end of theouter'sleeve 10 being provided with an outturned annular flange-12formingfal shoulder against which abuts the inner end f of they said hub11. This hub has lixed 'medially thereto outwardly extending radialspokes 13` with which is connected a felly A(not shown) in the ordinarywell-known manner.

A cap 14 is threaded to the slve 10 over I the flange 7, and said cap isprovided with an outwardly extending centrally located squared lug 15projecting 4from the outer l face of thev said cap to be engaged by awrench-or other suitable 'tool vwhereby the said cap 14 may be attachedand 'detached at will, the said cap serving as a dust proof closure forthe outer end of the hub. The

inner sleeve 6 is of considerably' greater length than the Vouter sleeve10 and has surrounding its inner end a' removablel -cap 16 the 'samebeing-provided with a circular iian'ge 17 projecting from one facethereof' Tand surrounding' theannularl flange, 12 at the inner end ofthe outer sleeve thereby eiiecting a dust proof closure for the inner lend ofthe hub. l

The inner cap 16 is provided with threaded apertures adapted to registerwith the. threaded apertures in the innerv sleeves 6' near its innerend. whereby the screws 9 may be passed through the capv for locking itto and against rotation on the inner end of the inner sleeve. The outercap 14 is adapted toy extend inwardly over the outer end of the outersleeve 10 and abutfagainst the outer end o f the hub 1.1.

It will be clearly seen that the hubof the wheel is prevented fromlongitudinal displacement on the axle by reason of the inner and outercaps and also that both ends ot' the hub are closed so that dirt, dustor other. foreign matter Will be excluded. Also it Will be observed thatthe inner sleeve (3 protects the journal end 5 of the axle therebyrelieving the same from Wear. The adjusting screws S) enables the hub tobe adjusted lorgitudinally on the journal end 5 of the ax e.

From the foregoing it is thought that the construction and operation ofthe invention will be clearly obvlous and therefore a more extendedexplanation has been omitted.

Having thus described 'my invention, what I claim is:

l.,V The combination with an axle; ofl a hub mounted for rotationthereon, an inner sleeve surrounding the axle and longitudinallyadjustable thereon, means locking the said inner sleeve against rotationon the axle, an annular flange formed at the outer end of said sleeve,an outer sleeve surrounding said inner sleeve and having its outer endabutting against said flange, an annular flange formed at the inner endof said outer sleeve and abutting against the vinner end of the hub andcaps detachably connected to the outer end of the outer sleeve and theinner end of the inner sleeve.

2. The combination with an axle; of a hub mounted :for rotation thereon,an inner sleeve `surrounding the axle and longitudinally adjustablethereon, means locking the said inner sleeve against rotation on theaxle, an annular flange formed at the outer end ot said sleeve, an outersleeve surrounding said inner sleeve and having its outer c end abuttingagainst said flange, an annular flange formed at the inner end of saidouter sleeve and abutting against the inner end of the hub, a capthreaded on the outer end of the outer sleeve for inclosing the flangeportion of the inner sleeve and a cap mounted Vupon the inner end of theinner sleeve and engaging the inner flange ofthe outer sleeve, said lastmentioned cap being held from rotation on the inner sleeve by thelocking means and having a forwardly extending flange, engaged by theperiphery of' the inner flange.

In testimony whereof, I aflx my signature, in presence of two witnesses.

MARTIN A. EWALD.
